Referring more in detail to the drawings:

The reference numeral 1 generally designates a roll feed end sheet machine for manufacturing end sheet structures 2 which may have such structure with a pair of folded sheets 3 and 4 in laterally spaced parallel relation. The folded sheets 3 and 4 are joined together by a tape 5 engaging exterior sides or surfaces adjacent folded edge portions 6 and 7 of the folded sheets 3 and 4 respectively. The end sheet structure 2 may also have interior sheets 8 and 9 tipped or glued to interior surfaces of the folded edge portions 6 and 7 respectively. The folded sheets 3 and 4 and the interior sheets 8 and 9 and the tape 5 are moved together in a finishing plane, as later described, where the respective components of the finished end sheet structure 2 are joined together.

The roll feed end sheet machine 1 has an elongate base frame 10 supported on a plurality of longitudinally spaced foundation plates or skids 11 for supporting the machine 1 on a floor or foundation (not shown). End frames 12 and 13 extend upwardly from the base frame 10 and are positioned at opposite ends thereof. An intermediate frame 14 is positioned between the end frames 12 and 13 and extends upwardly from the base frame 10.

Elongate support members 15 and 16 are positioned in the finishing plane and on opposite sides of the roll feed end sheet machine 1 and extend between and have opposite ends suitably secured to one of the end frames, as for example one end secured to end frame 12 and the other end secured to the intermediate frame 14, as by Welding. Elongate support members 17 and 18 are positioned in the finishing plane and at opposite sides of the roll feed end sheet machine 1 and extend between and have opposite ends suitably connected to the other end frame 13 and the intermediate frame 14, as by Welding. The end frames 12 and 13 and the intermediate frame 14 each are illustrated as having a pair of laterally spaced uprights 19 and 20 each having their lower ends mounted on the base frame 10 and their upper ends joined by an elongate upper transverse member 21 extending therebetween and suitably secured thereto, as by welding.

The portion of the machine 1 between the one end frame 12 and the intermediate frame 14 defines a preparation section wherein two rolls of paper or the like 22 and 23 are laterally spaced from opposite sides of the roll feed end sheet machine 1 and positioned adjacent one end thereof, as for example, between the one end frame 12 and the intermediate frame 14 with the rolls of paper 22 and 23 being mounted on supports 24 and 25 respectively. The webs of paper 22 and 23 each move under and engage guide rollers 26 and 27 respectively each of which direct the respective Webs 22 and 23 into web folding means, illustrated as folding shoes 28 and 29 respectively. The folding shoes 28 and 29 are each shaped to receive and fold the paper 22 and 23 and direct same to means for setting the fold to make same permanent as by creasing the folded edge portions 6 and 7 along a longitudinal fold line.

The folding shoes 28 and 29 are each triangular members having a receiving end at the base thereof. Flanges extend from the sides of the triangular member to engage opposite edges of the respective web of paper and direct same toward a discharge end at the apex of the triangular member while urging the opposite edges outwardly from the folding shoe.

The creasing means are illustrated as a first pair of elongate creasing rollers 30- each extending transversely between and having opposite ends rotatably mounted on the support members 15 and 16 and positioned to receive the folded paper 22 and crease same along a longitudinal fold line and a second pair of elongate creasing rollers 31 each extending transversely between and having opposite ends rotatably mounted on the support members 15 and 16 and positioned to receive the folded paper 23. The rollers in each of the pairs of creasing rollers 30 and 31 are urged toward each other and into engagement with each other under a suitable spring tension (not shown). The spring tension is such that the rollers permit the folded paper 22 and 23 respectively to pass therebetween while permanently creasing the folded edge portions 6 and 7 respectively along a longitudinal fold line.

The portion of the machine 1 between the intermediate frame 14 and the other end frame 13 defines a taping section for applying the tape to the adjacent edge portions 6 and 7 of the folded and creased paper 22 and 23 and moving same to cutting means for cutting the paper sheets and tape into end sheet structures of predetermined length, as later described.

The folded and creased paper 22 and 23 moves from the creasing rollers and 31 to idler or directing rollers 32 and 33 respectively for directing the folded and creased webs of paper 22 and 23 to a receiving end 34 of a pair of cooperating endless belts 35 and 36, upper and lower respectively, that move said folded and creased paper 22 and 23 longitudinally of the roll feed end sheet machine 1 while holding the adjacent folded edge portions 6 and 7 in spaced parallel relation with a predetermined spacing therebetween. The belts 35 and 36 hold said adjacent 39 and 40 positioned at opposite ends thereof for guiding the belts 35 and 36 in their respective endless paths therearound.

One of the end rollers in the upper and lower rows of rollers 37 and 38, as for example end roller 40, is a driving roller and is operatively connected with suitable driving means, such as a motor 41, in a conventional manner, as by endless chains and sprockets or the like. Tension is maintained in each of the belts 35 and 36 to hold the components of the end sheet structure 2 in clamped engagement between said belts 35 and 36 until the adhesive dries as by an adjustable roller 42 and a fixed roller 43 for each of the rows of rollers 37 and 38. Each adjustable roller 42 is mounted on a pair of adjustable arms 44 and a suitable fastening device, such as a bolt or screw 45, secures one end 46 of each of the arms 44 to the machine 1.

The bolts or screws are loosened to permit the arms 44 to pivot thereabout to the desired position engaging the respective belt 35 or 36 to adjust and maintain a desired tension therein. Each adjustable roller 42 is rotatably supported at the other end 47 of the respective pair of arms 44.

The taping section of the machine 1 has a reel 50 which is mounted adjacent the other end frame 13 and supports a roll of tape 51 which will become the tape 5 on the finished end sheet structure 2 and which may be plain or have suitable adhesive on one face 52 thereof. The tape 51 is fed from the reel 50 to an applicator 53 which applies a suitable adhesive, such as a quick-drying glue, to the one face 52 of the tape 51 or moistens an adhesive present on the face 52. The applicator 53 has a wheel 54 which has the periphery thereof positioned to engage the face 52 of the tape 51.

The tape 51 having the adhesive prepared on the face 52 moves to and engages the lower belt 36 adjacent the receiving end 34. The prepared tape 51 and the folded and creased webs of papers 22 and 23 move into the receiving end 34 and between the belts 35 and 36 where the rollers in the rows 37 and 38 press the face 52 of the prepared tape 51 into engagement with the adjacent fold ed edge portions 6 and 7.

It may be desirable for the end sheet structure 2 to have an additional tape 55 engaging interior surfaces of the folded edge portions with the tape 55 positioned opposite the tape 5, either with or without the interior sheets 8 and 9 attached thereto, therefore, a reel 56 is positioned above the upper belt 35 and supports a roll of tape 57 which will become the additional tape 55 and which may also be plain or have a suitable adhesive on one face 58 thereof. The tape 57 is fed from the reel 56 to an applicator 59 which applies a suitable adhesive, such as a quick-drying glue, to the face 58 or moistens an adhesive present on the face 58. The applicator 59 has a wheel 60 which is similar to the wheel 56 and which engages the face 58.

In the illustrated structure, the prepared tape 57 is then fed around a plurality of idler rollers 61 each of which are rotatably mounted and positioned to guide the prepared tape 57 into the receiving end 34 of the cooperating belts 35 and 36 with the one face 58 positioned to engage an interior side or surface of each of the folded edge portions 6 and 7 or adjacent edge portions of the interior sheets 8 and 9.

It is desirable to adjust the lateral or transverse spacing between the folded edge portions 6 and 7 of the creased and folded webs of paper 22 and 23 to conform to the thickness of material to be placed therebetween; therefore, upper ends of each of the folding shoes 28 and 29 are each adjustable transversely of the roll feed end sheet machine 1.

In the illustrated structure, elongate adjustment rods 62 and 63 each have one end pivotally mounted on the supports 24 and 25 respectively with the other end pivotally mounted on the folding shoes 28 and 29 respectively. Length adjustment means, such as turnbuckles 64 and 65, are mounted in the adjustment rods 62 and 63 respectively to adjust the position of an upper end 66 of the folding shoes 28 and 29 laterally relative to the receiving end 34. The folding shoes 28 and 29 each have a lower end 67 pivotally mounted on the supports 24 and 25 respectively whereby the upper ends 66 of each of the folding shoes are movable toward and away from each other to adjust and maintain a selected spacing therebetween and position same relative to the receiving end 34.

It is desirable to tip or glue the interior sheets 8 and 9 to the interior surfaces or faces of the folded sheets 3 and 4. Therefore, two rolls of paper or the like 68 and 69 are mounted on or adjacent the end frame 12. The webs of paper 68 and 69 move around an idler or directing roller 70 to an applicator 71 which applies a suitable adhesive, such as a quick-drying glue, to adjacent edge portions 73 and 74 of the paper 68 and 69. The applicator 71 has a wheel 75 similar to the wheels 54 and 60 with the periphery of the wheel 75 engaging the adjacent edge portions 73 and 74 at one face or surface 76 and 77 of the paper 68 and 69 respectively.

The paper 68 and 69 having the prepared edge portions 73 and 74 moves to the receiving end 34 of the cooperating belts 35 and 36 where the edge portions 73 and 74 engage the respective interior surfaces of the folded edge portions 6 and 7 to thereby provide the interior sheets 8 and 9 of the end sheet structure 2.

The transverse or lateral spacing between the adjacent edge portions 73 and 74 of the paper 68 and 69 is adjusted transversely relative to the folded edge portions 6 and 7 of the creased and folded webs of paper 22 and 23 to conform to the adjusted spacing therebetween.

In the illustrated structure, an elongate double threaded rod or shaft 78 has a pair of internally threaded sleeves 79 and 80 threadedly engaging the rod or shaft 78 for movement toward or away from each other upon rotation of the rod or shaft 78 by a suitable handle or crank 81. Cores 82 and 83 having the rolls of paper 68 and 69 mounted thereon are suitably rotatably mounted on the sleeves 79 and 80 respectively, as by bearings 84.

The reinforcing tape 57 may be applied to the interior surfaces of the paper 68 and 69 with a center portion of the tape 57 engaging and attached to a center portion of the tape 51 thereby providing an end sheet structure 2 particularly adapted to withstand severe use and provide long life for the item having the end sheet structure 2 therein, such as a book or the like (not shown).

It is desirable to adjust the spacing between the upper and lower rows of rollers 37 and 38 to maintain a substantially constant pressure on the components of the end sheet structure 2 moving the'rebetween, the spacing being determined by the number and thickness of the material moving between the upper and lower rows of rollers 37 and 38.

Therefore, the rollers in the upper row 37 each have their opposite ends rotatably mounted in parallel mounting bars 85 and 86. A plurality of support frames 87 are positioned above the mounting bars 85 and 86 and each have a transverse member 88 extending between laterally spaced uprights 89. Adjustment members 90 are mounted on the mounting bars 85 and 86 and extend upwardly and engage each of the uprights 89. The adjustment members 90 are each adjustably supported within the respective uprights 89 with suitable means to vertically move the mounting bars 85 and 86 and secure them in a selected position In the illustrated structure, the mounting bars 85 and 86 are moved vertically by adjusting screws 91 and when in selected elevation are secured by a respective nut 92 fixed on the adjustment members 90.

The selected combination of folded paper, tape, and paper for interior sheets to be tipped on the folded paper moves from a discharge end 93 of the cooperating belts 35 and 36 and moves over an elongate blade 94 extending transversely to the direction of movement of the paper and tape. A roller 95 is rotatably mounted above the elongate blade 94 and has a blade 96 mounted thereon whereby upon rotation of the roller 95, the roller blade 96 passes over the elongate blade 94 to cut the paper and tape positioned therebetween. The roller 95 is rotated at a predetermined speed whereby the paper and tape is cut into equal lengths. The speed of rotation of the roller 95 and blade 96 may be varied, as by gear changes, to vary the length of the finished end sheet structures 2.

In use, the rolls of paper 22 and 23 are mounted on the supports 24 and 25 respectively and the webs of paper 22 and 23 are moved through the folding shoes 28 and 29 and through the creasing rollers 30 and 31 respectively. The webs of paper 22 and 23 are then moved over the idler rollers 32 and 33 and moved toward the receiving end 34 of the pair of endless belts 35 and 36. The spacing between the folded edge portions 6 and 7 is checked at the receiving end 34. The spacing between the folded edge portions 6 and 7 is adjusted as necessary by the turnbuckles 64 and 65 to conform to the thickness of material to be placed therebetween. The tape 51 is moved to engage the applicator 53 to place or moisten a quickdrying glue on the one face 52. The tape 51 is moved from the applicator 53 to the receiving end 34 to engage the folded edge portions 6 and 7 for movement between the upper and lower row of rollers 37 and 38.

When it is desired to tip or glue the interior sheets 8 and 9 on the interior faces or surfaces of the folded sheets 3 and 4 the spacing between the rollers 37 and 38 is adjusted to conform to the additional thickness and the transverse or lateral spacing between the rolls of paper 68 and 69 is adjusted by the handle or crank 81 to properly space the edge portions 73 and 74 relative to the folded edge portions 6 and 7.

Should it be desirable to place the additional tape on the selected components of the end sheet structure 2 the spacing between the rollers 37 and 38 is adjusted as necessary. The tape 57 moves to and engages the wheel of the applicator 59 to place or moisten a quick-drying glue on the one face 58 thereof. The tape 57 is moved to the receiving end 34 of the cooperating upper and lower belts 35 and 36. The selected components are then moved through the belt conveying means to the cutting means where the blades 94 and 96 cut the components into the end sheet structure 2 of a selected length.
